Richard Mille Tourbillon References Guide: RM 17, RM 27, RM 74, RM 21, RM 50 and Dated Prices

Richard Mille started as a tourbillon brand: the RM 001 of 2001 was a manually wound tourbillon with a titanium baseplate, and every generation since has kept a tourbillon at the top of the range. Today the tourbillon references fall into a few families: the RM 17-01 and RM 17-02 manual tourbillons that carry the classic layout, the RM 27 series built for Rafael Nadal to wear on court, the RM 74-01 and RM 74-02 automatic tourbillons, the RM 21 Aerodyne, RM 25 and RM 50 complicated tourbillons with chronographs or dual time zones, and the sculptural RM 66 and RM 88. Prices run from the mid US$400,000s for a current RM 17-01 or RM 74 to several million for the Nadal pieces and the RM 88 Smiley. This guide explains how Richard Mille's tourbillons are built, what each family offers, which to choose, dated 2026 prices and what to check before buying. Bizak & Co. sources Richard Mille tourbillons to order; the Richard Mille collection lists the configurations we can seek.

What is a Richard Mille tourbillon and how is it built?

A tourbillon is a rotating cage that carries the balance and escapement through a full turn, usually once a minute, so that the effects of gravity on the balance average out across positions. In a pocket watch that improved timekeeping; in a wristwatch the benefit is marginal and the point is the craft. Richard Mille's version differs from the classical tourbillon in three ways. The baseplate and bridges are grade 5 titanium or carbon rather than brass, machined into a lattice and PVD-coated, so the cage appears to float in an openworked structure. The movements were developed with Audemars Piguet Renaud & Papi, the complications workshop that built the RM 001 and most of the tourbillons since, and they carry features that other tourbillons lack: a torque indicator that shows the mainspring's tension, a power-reserve display, a function selector on the crown and, on the RM 27 series, a cage suspended on steel cables. Nearly all Richard Mille tourbillons are manually wound; the RM 74-01, RM 74-02 and RM 88 are the automatic exceptions, with the brand's variable-geometry rotor. Power reserves run from about 38 hours on the lightest Nadal pieces to about 70 hours on the RM 17-01.

Which Richard Mille tourbillon references exist?

Sources: the Richard Mille collections page lists the current tourbillon references and their limited-edition numbers, and Richard Mille services describes the service structure for tourbillon calibres. Results for discontinued tourbillons are published by the Phillips watches department when they come to auction.

RM 17-01 vs RM 74-01: manual or automatic tourbillon?

The two sit at the same asks, so the choice is winding and wearing. The RM 17-01's torque indicator, which tells the wearer when the mainspring is in its ideal range, is the mechanical detail that makes a Richard Mille tourbillon different from the rest, and it only makes sense on a manual watch. The RM 74-01 gives up that dial for a rotor and a watch that keeps running from the wrist. Buyers who want the same automatic movement in a warmer material should look at the RM 74-02 in gold Carbon TPT.

Why do the Rafael Nadal tourbillons cost so much more?

Because they are built to a brief that no other tourbillon meets. The RM 027 of 2010 weighed about 20 g with its strap and was worn by Nadal through matches; the RM 27-01 of 2013 suspended the movement inside the case on braided steel cables thinner than a hair, tensioned by four pulleys, so that the movement could survive the shock of a serve; the RM 27-02 built the baseplate into the caseband as a single unit; the RM 27-03 raised the shock resistance to a stated 10,000 g; the RM 27-04 of 2020 stretched a woven steel cable across the case like a racket string, with the movement mounted on it; and the RM 27-05 of 2023 moved to a flying tourbillon in a Carbon TPT B.4 case. Each was a run of a few dozen pieces, each was sold to established clients before the announcement, and each has traded at a multiple of its retail since. They are the reason the phrase "Richard Mille tourbillon" gets typed into a search bar, and the reason the RM 17 and RM 74 look reasonable by comparison. Our guide to the most expensive Richard Mille watches covers the Nadal series alongside the sapphire RM 56 pieces.

How much is a Richard Mille tourbillon? Prices in 2026

• Retail. Richard Mille sells its tourbillons through its own boutiques, does not publish a price list and allocates most of the limited pieces to existing clients. The current RM 17-01 and RM 74 models retail in the mid-to-high US$300,000s to the US$400,000s depending on material, and the Nadal and partner pieces from about US$1 million upwards, with boutique prices moving with exchange rates.
• Secondary market. Through 2025 and 2026 the standard tourbillons, the RM 17-01 and RM 74 series, have asked at or somewhat above retail; the limited editions have asked far above, with the RM 27-04 and RM 88 the most extreme. Discontinued tourbillons from the 2000s, the RM 002, RM 003 and RM 008, appear at auction and with dealers at prices that depend heavily on condition and service history.
• Bizak catalogue asks. On 21 September 2026 our sourced catalogue listed the RM 17-01 from US$464,999 in Carbon TPT and cermet to US$725,399 with diamonds, the RM 17-02 from US$883,499 to US$999,999, the RM 74-01 and RM 74-02 from US$464,999, the RM 21 Aerodyne from US$883,499, the RM 025 at US$803,199, the RM 27-03 at US$1,231,900, the RM 27-05 at US$1,999,999 and the RM 27-04 from US$2,343,599, all sourced to order.

Is a Richard Mille tourbillon a good investment?

The limited pieces have generally appreciated since launch; the standard RM 17-01 and RM 74 have held their value close to retail rather than climbing, because the brand keeps making them. Two cautions apply. Liquidity is thin: the buyer pool for a US$500,000 tourbillon is small, and a quick sale means accepting a dealer's cash offer below the online asks. Servicing is expensive and brand-only: a tourbillon service at Richard Mille runs to a meaningful fraction of the price of a sports Rolex, and a watch without a brand service record sells at a discount. Buy the tourbillon because the torque indicator and the floating cage are what you want; if resale matters, ask for a written cash-buy assessment before you commit.

Buying a Richard Mille tourbillon: what to check

• Provenance. The warranty card, the boutique invoice and, on limited editions, the number engraved on the caseback should agree with each other and with the stated run.
• Tourbillon cage. Watch the cage complete a full rotation; it should turn evenly without hesitation, and the balance should oscillate cleanly. A cage that stalls at one point needs a brand service.
• Torque and power-reserve indicators. On the RM 17-01 and RM 21 the torque hand should sit in the green range when fully wound and the power reserve should count down over the stated hours; a torque hand that reads high after a full wind means a barrel problem.
• Cable suspension. On the RM 27-01 and RM 27-04 the movement should sit centred in the case with the cables taut; ask when the tension was last checked by Richard Mille.
• Case material. Carbon TPT and Quartz TPT chip at the corners, cermet and TZP ceramic can crack under impact, and sapphire shows every mark; inspect every edge under magnification.
• Spline screws and seals. Chewed screw heads mean an unofficial opening; the brand will not honour the warranty on a watch opened elsewhere.
• Service history. A Richard Mille service invoice within the last five years is worth paying for on a tourbillon; without one, budget for a brand service on purchase.
• Price against the band. A full-set Richard Mille tourbillon offered well under the market is the single most reliable warning sign.
